7 Claims.

This invention relates to cone rolling machines and particularly tomachines for forming cone shaped containers such as ice cream cones fromhot, freshly baked pastry wafers.

The apparatus of the present invention is an improvement on the conerolling machine shown in my Patent 1,720,304 issued July 9, 1929, andthe principal object of the present invention is to provide a simplifiedcone rolling machine of relatively compact and economical constructionby means of Which the rolled cones can be rapidly formed in a positiveand unerring operation.

Another object is to provide a cone rolling machine having a relativelysmooth operation and in which mechanism is provided for holding therolled cones under regulated pressure for a sufficient period of time toinsure proper hardening or setting of the formed articles before therelease thereof from themold' portions.

A further object is to provide a cone rolling machine with acontinuously rotating mandrel and die supporting drum, which is capableof providing a relatively smooth operation.'

AReferring to the-accompanying drawings, in f which like numeralsreferto like parts throughout the several views, the machine ofthepresent invention includes a frame I having upwardly projecting arms 2which rotatably support a longitudinally extending shaft 3 on which ismounted a mandrel carrying member 4 and a mold or die carrying member 5.The mandrel carrying member ,4 and die carrying member 5 are keyed tothe shaft 3 and the member 4 is provided with a plurality ofcircumferential teeth 6 which mesh with a drive pinion 'I carried by ashaft 8. The shaft 8 is journalled in a bracket 9 mounted on the mainframe I and is driven by a series of intermeshing gears I0 from a driveshaft I I, oneI of the gears being secured to the shaft I I and providedwith a series of radial clutch teeth I2 which are arranged to mesh witha clutch element I3 slidably mounted upon and driven by sub-shaft I lahaving one end rotatably mounted in the gear which carries the clutchteeth. 'Ihe member I 3 is slidably moved on the shaft I Ia by means of asliding member I4 which is actuated by means of a suitable clutch leverI5 pivoted to the frame I, as shown in Fig. 7.

The mold or die units IB are circumferentially arranged on the member 5and are conical shaped, each having a slot I1 therein and a loadingflange I8 forming one edge of the slot I'I. These mold or die units openthrough the member 5 to receive the conical rolling elements |9 whichare mounted upon rotatable mandrels 20. The mandrelsI 26 are journalledin suitable bearings 2| carried by the member 6 in a circumferentialmanner, the axis of each bearing 2| being coaxial with a correspondingmold or die unit I6. The mandrels 20' are rotatable in the journals 2|and are also movable longitudinally in the journals 2|. Each mandrel isprovided at its end, projecting through the journal 2|, with a circularcontrol disk 22 and a drive pinion 23 between the control disk andthejournal 2|, a coil spring 24 being interposed between the disk 22 andthe pinion 23. The pinion 23 is keyed to the mandrel 20 and the disk 22is movable on the mandrel 20 toward the pinion 23 against the pressureof coil spring 24. During the rolling operation, the control disks 22abut against a stationary annular cam 25 secured toI one of the arms 2,the cam 25 having a recess 26 therein of suicient depth to permit thecontrol disk 22 to be moved from a position such as shown in Fig. 1 toabutting engagement with the inner face of the cam 25. When the controldisk 22 is in this position, the mandrel 2D is yieldably urged towardthe die units I6. Y

The pinions 23 are rotated during a portion of their travel with themembers 4 and 5 by a gear 2'I mounted on a shaft 28 which is journalledin a bracket 29 secured to the arm 2. The shaft 28 is provided with a'sprocket 30 which is driven by means of a drive chain 3| from a sprocket32. The sprocket 32 is driven by suitable gearing 33 from the driveshaft II. At a predetermined period, the mandrels 20 are withdrawn fromthe die elements I6 and then reregister with these die elements. Themeans for accomplishing this comprises a parallel linkage 34 pivoted atthe lower end to a bracket 35 secured to the frame and having at itsupper end a grooved block 36 having a groove 3'I therein of suii'icientwidth to receive thecontrol disk 22 of each mandrel 2U as the mandrelrotates with the members 4 and 5. The block 36 is provided with a recess38 at its upper end which opens into the groove 31 as shown in Fig. 8.

The linkage 34 is caused to travel longitudinally of the machine bymeans of a disk 39 having a rotatable block '40A thereon' which isarranged to have sliding movement on'on'e of thebars of the linkage 34.Thedisk 39 is mounted on a shaft 4| journalled in a bracket 42 securedto the side frame I. The shaft 4I is driven by means of bevel gears 43from the shaft I I. A latching dog 44, as shown in Fig. 4, is pivoted tothe stationary cam 25 at the upper edge of the recess 26 and is held ina normal position by a coil spring 44a to assist in the movement of themandrels 28 relative t the members 4 and 5.

Each of the conical members |9 which registers with the die element I6is provided as shown in Fig. 19 with a series of ridges in the form ofwires 45 that serve to engage 'the wafer to draw it into the moldingcavity when the mandrel is rotated. The ridges formed by the wiresterminate near the central zone of the member I9 in order that they maypartially imbed themselves in the pastry of the formed cone and carrythe cone out of the mold when the mandrel is that are carried by theshaft 3 in any suitable manner, as shown in Figs. 1 and 18, engage theopen end of the formed pastry cone when the mandrel 20 is drawn out ofthe mold by the operation of the linkage 34. rlhe fingers follow thelongitudinal contour of the rolling member I9 to drag the formed conesfrom the member I9 and permit them to fall upon an underlying conveyorbelt 41 which is driven by a ratchet mechanism 48 from the shaft 8.

In order to assist in feeding the wafers into the slots I'I of the dieelement I6, a suitable feed table 49 is provided. This feed table 49 ismounted upon an arm 50 pivoted to the shaft 3 and is raised by means ofa ratchet gear 5| secured to the shaft 3. The arm 59 is provided with aspring pressed dog 52 which is arranged to engage with the teeth of theratchet gear 5|, as shown in Fig. 17. The dog 52 and ratchet of the gear5I, when they engage, raise the table 49 upwardly to a position such asindicated in Fig. 13, and during this movement the wafer to be rolledinto a cone is manually slid from the table 49 onto the feed flange I8of the element I6 and into the slot I'I. As they uppermost position ofthe table 49 is reached, the dog 52 is thrown out of engagement with theengaging teeth of the ratchet gear 5| bymeans of a suitable cam 53, andthe table 49 then drops to its lower position. The downward position ofthe table 49 is limited by means of a, member 54 carried by a rod 55which is pivoted at 56 to the arm 58. The hinged connection 56 ispreferably arranged at a slight anglew'ith respect to the movement ofthe arm 50 so that, as the table 49 approaches its lowermost position aslight friction is exerted to allow the table to gradually assume itslowermost position. Also, the stop member 54 may be of rubber or othersuitable material if desired, to prevent a jarring movement when thetable 49 reaches its lowermost position.

In order to properly time the machine, the ratchet gear 5I, as shown inFig. 14, is arranged to be adjustably rotated, and for this purpose theratchet gear is mounted upon a disk 5I having slots 58 therein, the gear5I being secured to the disk 5'I by bolts 59 whichv extend through theslots 58.

Similarly, the disk 39 which drives the linkage 34 is adjustably mountedon a ilanged collar 60 carried by the shaft 4|, as shown in Figs. 1l and12, the collar 60having slots 62 therein and the disk 39 being securedto the collar 60 by means of cap screws 63 which extend through theslots 62 and thread into a suitable plate 64.

It will be noted in Fig. 3 that some of the teeth 65 of the mandreldrive gear 2I are cut away for a portion of their depth, one tooth beingcut away substantially to its pitch circle and the succeeding teethbeing of gradually increasing depth. This is for a purpose which Will beseen in the description of the operation of the machine.

The shaft 3, together with the members 4 and 5, is continuously rotatedand the mandrel drive gear 21 is also continuously rotated and the pitchcircle of the drive gear 2'I is substantially tangent at predeterminedtimes to the pitch circle of each mandrel pinion 23, as shown in Fig. 2,so that as the pinions 23 are bodily moved in a circular path past thegear 2'I the teeth of the pinions and drive gear 2'I will engage andcause Va rotation of the mandrel, which rotation causes the wafer thatis fed into the slot of the die element I6 to be rolled within the dieelement to produce the rolled cone 66 shown in Fig. 21.

As viewed in Fig. 2, the shaft 3 rotates in a clockwise direction DuringtheV operation of the machine, the wafer from which theK cone is to beformed is moved into the slot I'l ofV the die element I6 as the table591 moved. upwardly, and as the correspondingmandrel is being rotated bythe gear ZT, which causes the mandrel 20 to rota-te during the timethat. the gears 23'. and 2T= are meshed with each other. The members diand 5 then carry. the mandrel: in a clockwise direction,

as viewed in Fig- 2, from the position indicated' at A to a position B,at which time the linkage 341 hasv moved the block 365 inwardly so thatthe groove 312 thereof is in a position tov receive the control disk 23.of the mandrel C approximately as the disk 23'V clears; the edge oftherecess 26, in the` camf25; Then, during aportion of further travel ofthe mandrel C, the linkage 3d moves outwardly and carries themandrelC'in an out ward direction soi thatv the cone Sii carried by the rollingelement I9 is stripped from the element I9 by means of the fingers: 4,6.During continued movement of the mandrel in a clockwise direction, thelinkage 34 then moves the mandrel inwardly so that the teeth of thepinion 2-3 engage with the mandrel drive gear 2l, at which time therolling element. i9 is registered. with the correspending die elementyl-B to roll another cone.

Inasmuch as the' mandrel is moved to its inner position with a slightpressure caused by the spring. 24p thel latchjmeans 44 is provided toprevent outward movement of the mandrel during the time the control diskleaves the groove block 36 to engage with the inner face of thestationary cam 25.

It will be noted that the pinions 23 bodily move in an annular pathabout gear 2l which successively rotates them during a portion of theirtravel and that the pinions during their travel are successively causedto engage with and disengagel from the gear 2l. In order to avoidclashing and interference of the teeth of the respective gear andpinions as the pinions are disengaging from and moving in their annularpath bodily away from the gear 27, some of the teeth 65 of the gear 2lare cut away for a portion of their depth, as shown in Fig. 3. Aspreviously explained-one of these teeth is cut away substantially to itspitch circle and the succeeding teeth at one side gradually increase tomaximum or full depth at the addendum circle. This permits a positiveand sudden disengagement of the teeth of each pinion 23 from the teethof the gear 2l and insures that the tips of the teeth of the gear andpinions will not interfere with each other as they are being disengagedduring the annular travel of the pinions 23 away from the gear 21.

In Figs. 2 and 1a I have shown a means for rotating the mandrelsslightly as they are bodily moved, in order to prevent the cake or bakedbatter being rolled from becoming too rmly set in the molds or dieelements I6. This means may comprise a pair of arms 'lil carried by theshaft journal of the member 2, each arm having an4 element 1I pivotedthereto and urged to a normal position by a spring 12. As the gears 23are moved throughout the circular path during rotation of the shaft 3,the elements 'il engage with the teeth of the gears 23 and cause thesame to rotate a slight amount. This will prevent the rolled cone frombecoming set too firmly in its die element I6, thus permitting easierwithdrawal of the cone from its die element I6.

It will be noted from they foregoing descrip-tion that I have providedan improved cone rolling mechanism in which the aligned rolling mandrelsandi die elements arelcontinuously moved in a circularpath withoutinterruption andv in which the mandrels are-reciprocated longitudinallyto strip the. rolled'` cones andthen moved back to their normal?position at pretedermined periods for a subsequent cycle of'v individualrotation during which time the: rotation of element i9 by the mandreldraws the water into the die element iii where it is rolled andmaintained under molding pressure long enough-to properly cool andassume the desired permanent shape before it is ejected uponv the nextsubsequent outward reciprocation of the mandrel 20.

The cone rolling machine of the present invention is capable` ofrapidlyproducing pastry cones during a smooth and positiv-e operation, A verylarge number of such cones can be readily produced by the machine in ashort time and in fact, it has been found in'commercial operation thatthe machine is capable of forming cones as rap idly as the cakes orwafers can be baked in the improved forms of baking machines nowavailable.

Although a single embodiment of the invention has', been herein shownand described, it will be understood that' numerous details of the construction shown may be altered or omitted without. departing from thespirit of this invention as defined in the-following claims.
